said window to any desired elevation and thelatching of the window atsuch point, the latching means being largely concealed within the sashand also being adapted to form a corner fastening or cornerreinforcement of the sash. The invention also includes certain featuresof construction which particularly adapt the same for use uponautomobile busses, street cars and the like.

The invention also includes a sash formed of; extruded metal strips,preferably of alu- .minum or aluminum alloy, said strips being for mostuses of identical cross-section for the side, top and bottom sashmembers, although where an auxiliary sash is employed,

as in automobile busses or the like, strips of I able.

modified cross-section may. be found desir- The sash members thus formedare preferably provided'with grooves or channelways on the outer andinner lateral sur- 1 faces which. reduces the amount of metal requiredfor the window construction to a minimum and at the same time'causes theframe members to have a finished and artistic appearance, as well asadequate degree of strength for the purpose intended.

The invention also contemplates providing one removable sash member and1n the preferred constructlon includes the provlsion of separable jointsat two corners of the sash and welded joints at the opposite cornersthereof, thus providing a rigid thoroughly braced structure and at thesame time permitting free access to the glass, permitting itsinstallation orremoval at aminimum of effort and expense. The inventionalso includes the mitering of the frame members preferably at the uppercorners of the win- .dow to permit the fastening thereof by securingmembers such as machine screws, or

the like, set diagonally through the solid portions of thestrips, aportion of thehead Serial No. 261,435.

of each screw projecting and being. engaged by the rubber buffer stripsinserted within the adjacent groove andbeing locked againstdisengagement from such framemembers.

In addition to simplifying the corner construction of the window,.theuse of solid ex-- truded. metal sections of substantially Hcross-section with the central portion of greater thickness than theremaining portions of the structure provides a rigid window frame whichmay be identical in crosssection for both the lateral and top and bottommembers, and requiring a minimum quantity of materialand at the sametime providing for engagement of the lateral members with grooved guidemembers and of the top and bottom members with suitably shaped rubberclosure strips. To the accomplishment of the foregoing and related ends,said invention, then, consists of the means hereinafter fully describedand particularly pointed out in the claims.

The annexed drawing and the following description set forth in detailcertain mechanism embodying the invention, such disclosed meansconstituting, however, but one of various mechanical forms in whichtheprinciple of the invention may be used.

' Fig. 10 is an enlarged detail view partially in section taken alongthe line 1010 shown in Fig. 6, looking in the direction of the arrows;and Fig. 11 is a perspective view of the latching mechanism.

As is clearly shown in Fig. 1 of the drawing, the window constructioncomprises a lower sash 1 and an'upper' sash 2 positioned in a suitableopening in a framed structure3. The lower sash is preferably formed offour strips of metal 4, 5, 6, 7, preferably of "extruded aluminum, orsuitablesalloysthereof, each strip having a cross-section of H type withthe transverse portion of greater thickness than theremaining'elements'and having a depression or groove 8,-centrally ofeach inner and outer 'face'toreduce the amount of metal in the structurewithout sacrificing its strength-or detracting from'its appearance Eachof'said strips preferably is'mitred at forty-five degree angle atthe'respective ends. -Them1tred sections when united are held in rightangle relation to eachother-by suitable fastenlng-me'ans. Thelower'corners 9, 10, may he -welded, ormay be otherwise secured; Alatching device 11 is'pr'eferably secured'to each lower corner and willserveto reenforce the adjacentcorner. The latching devicealonemightserve as the corner fastening but" the corners'are preferablywelded "-and 'the latchin device'is a lied thereo ver serving to-furtherbrace'and support the same.

The upp'ercorners =12, 13, are-preferably supplied with removable'securing means, which permits the ready removal'of the top sash member 7Each upper corneris'preferably secured by means'o'f' a fastening member14- inserted diagonally -through such corners at the point where thesolid "portions '15 of'the strips meet. 'An aperture 16 is formedthrough thesolid portions of the adj acent strips, such aperturebeginning at the base of the groove '17 in the top section, preferablyadjacent each of the respective'corners, and extending diagonallythrough the adjacent ends'of the side strips. The bore to receive thefastenin memberma eXtend com letel b i ingelement. Such elementpreferably comprises a machine screw 18 having alarge head -19 whichprojectsslig'htly into the groove 17 for the rubber closure strip 21 atthe top of thesash when the corners are securely united. v

' The construction, as has been indicated,

'involvesithe insertion of the glass 22 within thelower windowagainst'the adjacent window frame when lb is in raised orloweredposition. The rubber closure strip at the top of the window comprises aflat section 24 to which is united a substantially cylindrical bead 25secured at one side to said flat section and said bead is forced intosecure engagement within the groove of the removablemember of the'windowsash,'which, 'as'is-shown, is of somewhatmore than semi-circulareXtentin CIOSS-SQCEIOH. This firm engagement" of the head of the rubberstrip within the outer groove of the removable-member provides a directpressure upon the'proJectmgedge of the diagonal fastening"member-andeffectively prevents said fastening'member bey coming loosened throughcontinued vibration of the parts.

A similar strip having a substantially cylindrical bead 26 is engagedwithin the groove at the lower edge of't'hesash toform" a clothe membersare of identical cross section,

the-upper and lower outer. grooves *receiving the rubber closure stripsand the outer'l'ater'al grooves being adapted to engage'with thesubstantially cylindrical beads '28 on the resilient guide members 29-attached'to each v side of the windowkfraine' -and-preferably held byvertical securing strips 80 attached by suitable fastening elements.=Therguide grooves are reamed 'at the corners 'where the 'initred edgesoverhang.

The upper sash may correspond in structure to the lower and bevertically slidable on guide members, but in constructions-suitable forauto bussesystreet cars and the like, a stationary uppersash is morefrequently used.

For an upper sash of this character the metalsections be modified attheir outer edges to provide an angle member 31 atthe outer edge ofthetop'andside members 32, '33, 34,-and'a rounded lower edge 'atthe ba'se36 of the stationary sash, Thisedgeinay have a hollow center40'tosavemetalg'as is clearly shown in Fig. 2 of the'drawing. P lheupper sash is preferably secured to the outside of thefra'me'by means ofscrews orother fastening members engaged throu'gh suitable openings intherespectiveflanges; I I

The corners 'of'the upper sash are secured in substantiallythe same wayas in thelowelr '1;

sash, one side, preferably the bottom member, being removable to permitthe installation of the glass, which is preferably inserted in the innergroove of the sash member and cushioned with a liner of glazing rubberor similar material. The liner 37 inserted within the inner groove ofthe lower strip of the upper sash member is preferably provided with anextension flange 38 against which the extension flange 24 of the closurestrip is adapted to abut to form a weather-tight seal when the window isclosed. Lock washers may be used on the diagonal fastening members whenthe rubber closure strip is not used in the bottom member of the uppersash.

The upper sash members are also prefer ably formed of extruded aluminumstrips, the lateral faces of which are grooved or channeled similar tothe sash members of the lower sash to provide for a minimum weight ofmaterial as well as an improved appearance without sacrificing anystrength in the structure. It will be noted in each construction thatthe depressed portion of the sides of the sash members are joined withthe flanges forming the inner and outer portions of said members upon aradius which meets the solid body portion of such members at pointsspaced from the base of such flanges to provide adequate strength atsuch points.

The lower corners of the main sash, as has been indicated, arepreferably provided with latch members which form corner reinforcementsas well as fastening means. As is clearly shown in Fig. 11 of thedrawing, the latch comprises a base plate 41 having a vertical arm 42adapted to rest in the groove of the adjacent vertical sash member and ahorizontal arm 43 adapted to engage the curved portion of the inner sashadjacent the glass. The vertical arm carries a journal 44 for the latchbar 45 which is provided with an upstanding rib 46 forming a shoulderabutting the inner face of said journal. The horizontal arm is providedwith a flange 47 forming a lifting member to raise the sash. The baseplate is secured by suitable screws to the respective sash members. Inline with the journal and the latch bar an aperture is formed in theadjacent vertical sash member to receive a cylindrical locking dog 48formed integrally with the inner end of the latch bar.

A coiled spring 49 is adapted to be engaged about the central portion ofthe latch bar between the upstanding rib and the cylindrical lockingdog. One end of the spring is adapted to be received in an aperture 51on the inner face of the locking dog and the other end in an aperture 52adjacent the journal in the vertical arm of the base plate. A recess 53provided on the inner face of the vertical arm in alignment with thejournal is adapted to form a housing for the spring. The outer end ofthe latch bar is provided with a tapered head 54 having a ribbed portion55 over which is engaged a latch release arm 56 havlng an openmgsimilarly ribbed to engage the same. A set screw 57 engaged in an aerture in the end of a latch bar serves to holc the latch bar,spring,and latch rean arcuate portion 62 which is adapted to engage oneof a series of locking apertures 63 formed in the respective verticalguide members of the lower sash.

It will be understood that the arcuate portions of the locking dog areforced outwardly by the coiled spring and engage the adjacent aperturesof the lateral guide members to hold the lower sash to any desiredposition of adjustment. hen it desired to change the position of thelower sash, the release arm of the latches at the respective lower oursof the sash are depressed toward the lifting members and the flat facesof the cylindrical locking dogs are turned to vertical position, and insuch position clear the ad jacent guide members, leaving the lower sashfree to be adjusted to any desired position.

Other modes of applying the principle of my invention may be employedinstead of the one explained, change being made as regards the mechanismherein disclosed, provided the means stated by any of the followingclaims or the equivalent of such stated means be employed.
